Oil Charge — The 19XL compressor holds approxi-

mately 8 gal. (30 L) of oil. The chiller will be shipped with

oil in the compressor. When the sump is full, the oil level

should be no higher than the middle of the upper sight glass

and minimum level is the bottom of the lower sight glass

(Fig.2A or 2B). If oil is added, it must meet Carrier’s speci-

ﬁcationfor centrifugal compressor usage as described in the

Oil Speciﬁcation section on page 63. Chargethe oil through

the oil charging valve, located near the bottom of the trans-

missionhousing (Fig. 2A or Fig. 2B). The oil must be pumped

fromthe oil container through the charging valve due to higher

refrigerantpressure. The pumping device must be able to lift

from 0 to 200 psig (0 to 1380 kPa) or above unit pressure.

Oil should only be charged or removed when the chiller is

shut down.

PowerUp the Controls and Check the Oil Heater

—Ensure that an oil level is visible in the compressor

before energizing controls. A circuit breaker in the starter

energizes the oil heater and the control circuit. When ﬁrst

powered, the LID should display the default screen within a

short period of time.

The oil heater is energized by powering the control cir-

cuit. This should be done several hours before start-up to

minimize oil-refrigerant migration. The oil heater is con-

trolled by the PIC and is powered through a contactor in the

power panel. Starters contain a separate circuit breaker to

power the heater and the control circuit. This set up allows

the heater to energize when the main motor circuit breaker

isoff for service work or extended shutdowns. The oil heater

relay status can be viewed on the Status02 table on the LID.

Oilsump temperature can be viewed on the LID default screen.

When the Time/Date is conﬁgured for the ﬁrst time or if

power is lost for more than 3 hours, the oil heat algorithm

will take effectbefore the compressor can start. See the Oil

Sump Temperature Control section on page 32 for addi-

tional information. The oil pump will then energizefor 1 to

2 minutes to bring the oil temperature to normal operating

temperature.A LOW OILTEMPERATURE alert will show

onthe default LID screen if the operator has the controls set

to start.

SOFTWARE VERSION — The software version will

always be labeled on the PSIO module, and on the back

side of the LID module. On both the Controller ID and LID

ID display screens, the software version number will also

appear.

Set Up Chiller Control Conﬁguration

Do not operate the chiller before the control conﬁgu-

rations have been checked and a Control Test has been

satisfactorily completed. Protection by safety controls

cannot be assumed until all control conﬁgurations have

been conﬁrmed.

Asconﬁguration of the 19XL unit is performed, write down

all conﬁguration settings. Alog, such as the one shown on

pages CL-1 to CL-2, provides a convenient list for conﬁgu-

ration values.

Input the Design Set Points — Access the LID set

pointscreen and view/modify the base demand limit set point,

andeither the LCW set point or the ECW set point. The PIC

cancontrol a set point to either the leaving or entering chilled

water.This control method is set in the Equipment Conﬁgu-

ration table, Conﬁg table.

Inputthe Local Occupied Schedule (OCCPC01S)

—Access the schedule OCCPC01S screen on the LID

and set up the occupied time schedule per the customer’s

requirements. If no schedule is available, the default is fac-

tory set for 24 hours occupied 7 days per week including

holidays.

For more information about how to set up a time sched-

ule, see the Controls section, page 11.

The CCN Occupied Schedule should be conﬁgured if a

CCN system is being installed or if a secondary time sched-

ule is needed.

NOTE:The default CCN Occupied Schedule is OCCPC03S

forSoftware Version 09 and above; the default is OCCPC02S

for Software Version08 and below.

SelectingRefrigerant Type — The 19XL control must

beconﬁgured for the refrigerant being used, either HCFC-22

or HFC-134a.

TOCONFIRM REFRIGERANT TYPE — Conﬁrm that the

correct refrigerant type is indicated by entering the Controls

Test tables on the Service menu, Fig. 17. Select REFRIG-

ERANT TYPE. The screen will display the current refrig-

erant setting. Press EXIT softkey to leave the screen with-

out changes.

TO CHANGE REFRIGERANT TYPE — Enter the Con-

trols Test tables on the Service Menu. See Fig. 17. Select

REFRIGERANTTYPE. The screen will display the current

refrigerant setting. Press YES softkey to change the cur-

rent setting. Next, move to the ATTACHTO NETWORK

DEVICE screen on the Service menu and theATTACH TO

LOCAL DEVICE to upload the new refrigerant tables.

InputService Conﬁgurations — The following con-

ﬁgurations require the LID screen to be in the Service por-

tion of the menu.

• password

• input time and date

• LID conﬁguration

• controller identiﬁcation

• service parameters

• equipment conﬁguration

• automated control test

PASSWORD— When accessing the Service tables, a pass-

word must be entered. All LIDs are initially set for a pass-

word of 1-1-1-1.This password may be changed in the LID

conﬁguration screen, if desired.

INPUT TIME AND DATE— Access the Time and Date

table on the Service menu. Input the present time of day,

date, and day of the week. ‘‘HolidayToday’’should only be

conﬁgured to ‘‘Yes’’if the present day is a holiday.

CHANGELID CONFIGURATION IF NECESSARY— The

LIDConﬁguration screen is used to view or modify the LID

CCN address, change to English or SI units, and to change

the password. If there is more than one chiller at the jobsite,

change the LID address on each chiller so that each chiller

hasits own address. Note and record the new address. Change

the screen to SI units as required, and change the password

if desired.
